The ion–molecule reaction between six hexachlorobiphenyl positive molecular ions and ammonia in a triplequadrupole instrument to yield [M + NH 3 – HCl] +. ions gives products whose abundances differ by at least an order of magnitude under uniform conditions. This reaction offers a way of distinguishing many isomers by a reaction that is different from the other demonstrated route, the loss of HCl from [M + O – Cl] − ions.
